粒重是大小麦产量构成的因素之一,为此我们从1979年开始,对不同类型的大小麦进行了施粒肥的研究。通过6年试验,初步明确,像浙麦2号、浙皮1号等粒重偏低的品种,其增产作用较为显著。为进一步证实和明确施用粒肥的增产可靠性以及经济效益和生理依据,我们在1983和1984二年中对大麦浙皮1号施用粒肥的增产效应进行了较深入研究。现将结果整理如下。
Grain weight is one of the factors that make the wheat yield of large and small wheat. Therefore, we started to study the fertilization of different types of large and small wheat from 1979. Through six years of experiments, initially clear, such as Zhejiang wheat 2, Zhebai No. 1 and other low grain weight varieties, the more significant role in increasing production. In order to further confirm and clarify the reliability of yield increase of grain fertilizers and their economic benefits and physiological basis, we conducted a more in-depth study on the yield-increasing effects of applying barley fertilizer to Barley Zhepi 1 in 1983 and 1984. The results are now organized as follows.
